Therefore, the influence of static electricity on the signal line on the signal line flexible substrate 501 can be eliminated. In particular, since the sheet metal extension 602 is wider than the signal line flexible substrate 501, the static electricity that has entered from the gap 402 easily flows to the sheet metal extension 602, so that the function as a lightning rod can be surely exhibited.

Abstract

La présente invention concerne un dispositif de terminal mobile capable d'éliminer les influences de l'électricité statique des substrats flexibles de la ligne de signal agencés via une partie de connexion raccordant deux boîtiers d'une manière où ils se chevauchent librement, sur les lignes de signaux. Dans le dispositif de terminal mobile, l'un et l'autre boîtier (300) sont reliés de manière à se chevaucher librement via la partie de connexion (400), et les substrats flexibles de la ligne de signal (501) pour relier les substrats de circuit accommodés individuellement dans l'un et l'autre boîtier (300) sont agencés via l'intérieur de la partie de connexion (400). Le dispositif de terminal mobile comprend une paire de substrats flexibles mis à la masse dans une coque (502) et rendus plus larges (avec un motif conducteur mis à la masse à la coque) que les substrats flexibles de ligne de signal (501) pour ainsi serrer les deux faces extérieures des substrats flexibles de ligne de signal (501).
